Control Arm Ends - Rubber or Flex?

I'm looking at replacing my stock control arms with adjustable arms. I need opinions on which is better way to go. Flex end/Johnnie Joint or the rubber bushing ends? I assume the Flex ends are called that because they flex better, but do they have drawbacks other than slightly higher cost? Do rubber ends ride better/less noise?

Flex joint in one end, rubber bushing on the other. The increase in NVH is minimal compared to having rubber bushings at both ends. No real drawbacks with the flex joints.

I've run JJs (real ones not any of the imitations) on both ends of control arms and been happy. Lots of good things in JK and TJ world being said about the new Metalcloak joints.
